My System is Therapist And I am it's Worst Patient

Kang Rieon killed one thousand eight hundred and forty-seven people. He never felt a single thing about any of them — no fear, no guilt, no thrill. He simply never learned how. Then he dies — and wakes up as Kael Rhodes, the "useless" third son of a Viscount house buried in debt, seconds before someone tries to poison him too. Old habits solve that problem fast. But dying didn't free him. It introduced him to the Empathy Protocol — a System that doesn't reward kills, cunning, or power. It rewards feelings. Real ones. And it's infuriatingly good at catching him whenever he tries to fake one. Now Kael has to out-scheme debt-trapping nobles, survive a political game with real knives in it, and rebuild a dying house from nothing — all while a sarcastic voice in his head insists on turning the world's most efficient killer into an actual person, one uncomfortable emotion at a time. He's the greatest manipulator this world has ever seen. He just has a terrible therapist he can't fire.
